    SOLVED.

    Everything is ok , but i used a 4 Ohm resistor in R5, bad marked on the package.

    This produces no sound on my system.. Once set up the proper value everything was fine :)..


    So Urbancamo design works! And programming directly from TL866 is quick and easy if anyone is interested. I've tried Avrdudes, ProgIsp, avrdude cmdline too.


    Thanks Crisp for your support!

    Hi! Thank you ! I will retry with the last design available then. In the meanwhile , i checked the traces and it seems ok with the last official, so i can say it should be ok..

    I heard the tone only without fuse setting...


    Maybe something i do wrong in setting those ones?


    I changed Crystal, progammed with tl866 and with usbasp. I'm using atmega88pa.. Using 0xe0 as low and 0xdf as high fuses. No change to extended..

    Can you suggest me a configuration (fw and fuse) that should work for sure?


    Thanks

    Stefano

    Sorry:

    avrdude -c usbasp -p m88p -U lfuse:w:0xe0:m -U hfuse:w:0xdf:m

    using ATMEGA88PA-PU

    Sorry to post this thread, i tried the Urbancamo design, the latest firmware, but no sound with:


    avrdude -c usbasp -p m88 -U lfuse:w:0xe0:m -U hfuse:w:0xdf:m


    Any help?


    Thanks a lot
